[Soraoto snickers a small bit but then it drops at Yusei's words. What is WRONG with these people?]

Hm? Really?
Alright, how about this one:

There are two guys drinking at a bar. One starts to insult the other one screaming, "I slept with your mother!"

The bar gets quiet as everyone stops to watch and listen to see what the other man does. The first man then yells once more, "I SLEPT WITH YOUR MOTHER!"

Finally, the other says,

"Go home dad you’re drunk."
